The device’s inventors suggest the laser could find use in video displays, solid-state lighting, and a laser-based version of Wi-Fi.

Although previous research has created red, blue, green and other lasers, each of these lasers usually only emitted one color of light. Creating a monolithic structure capable of emitting red, green, and blue all at once has proven difficult because it requires combining very different semiconductors. Growing such mismatched crystals right next to each other often results in fatal defects throughout each of these materials.

But new research proves that, with a little training, adults can learn how and that the effect can last for months.

Ross Perot’s staffers did just that in 2006, when their boss declared that he wanted to decorate his Plano, Texas, headquarters with relics from computing history. Aware that a few measly Apple I’s and Altair 880’s wouldn’t be enough to satisfy a former presidential candidate, Perot’s people decided to acquire a more singular prize: a big chunk of ENIAC, the “Electronic Numerical Integrator And Computer.” The ENIAC was a 27-ton, 1,800-square-foot bundle of vacuum tubes and diodes that was arguably the world’s first true computer. The hardware that Perot’s team diligently unearthed and lovingly refurbished is now accessible to the general public for the first time, back at the same Army base where it almost rotted into oblivion.

So sad to hear Intel is going out of the mobo business. True, some were duds, but overall, my lappy's Intel and my desktop Intel have held out remarkably well over the years (they're both c.2008) and have accepted at least 3 iterations of Windows, 3 different Hackintosh versions and any Ubuntu since 8.10.

SonicSpike writes: A Houston man has been arrested after Google sent a tip to the National Center for Missing and Exploited Children saying the man had explicit images of a child in his email, according to Houston police.

The man was a registered sex offender, convicted of sexually assaulting a child in 1994, reports Tim Wetzel at KHOU Channel 11 News in Houston.

"He was keeping it inside of his email. I can't see that information, I can't see that photo, but Google can," Detective David Nettles of the Houston Metro Internet Crimes Against Children Taskforce told Channel 11.

After Google reportedly tipped off the National Center for Missing and Exploited Children, the center alerted police, who used the information to get a warrant.

A search of the man's other devices revealed more suspicious images and text messages. Police arrested him and he's being held on a $200,000 bond.

On one hand, most people would certainly applaud the use of technology to scan email in a case like this.

On the other, debate rages about how much privacy users can expect when using Google's services like email. In a word: none.

A year ago, in a court brief, Google said as much. Then, in April, after a class-action case against Google for email scanning fell apart, Google updated its terms of service to warn people that it was automatically analyzing emails .

Considering Google has been working to fight online child sexual abuse since 2006, it stands to reason the company would scan emails looking for those sorts of images. Google has never come right out and said so, but hinted strongly at it about a year ago when Jacquelline Fuller, director of Google Giving, specifically mentioned the National Center's "CyberTipline" in a blog post . The CyberTipline receives leads and tips regarding suspected crimes.

An anonymous reader writes: Even though Modern humans started appearing around 200,000 years ago, it was only about fifty thousand years ago that artistry and tool making became popular. New research shows that society bloomed when testosterone levels in humans started dropping. A paper published in the journal Current Anthropology, suggests that a testosterone deficit facilitated the friendliness and cooperation between humans, which lead to modern society. “Whatever the cause, reduced testosterone levels enabled increasingly social people to better learn from and cooperate with each other, allowing the acceleration of cultural and technological innovation that is the hallmark of modern human success,” says University of Utah biology graduate student Robert Cieri.

schwit1 writes: Vitaly Lopota, the president of Russia’s largest space company Energia, was suspended Friday by the company’s board of directors.

The move appears to be part of an effort by Russia’s government to obtain majority control over Energia, of which it owns a 38-percent share. The directors elected Igor Komarov as its new chairman of the board. Komarov is chief of the Russian United Rocket and Space Corporation (URSC), the government-owned company tasked with consolidating Russia’s sprawling space sector.

The government is also conducting a criminal investigation of Lopota, which might be justified but appears to be a power play designed to both eliminate him from the game as well as make sure everyone else tows the line so that URSC can take complete control.

Yesterday was also the 52nd anniversary of the launch of the Telstar-1, the world's first active telecom satellite, the world's first privately-ventured space-faring mission and first commercial payload into space.

PS: Does anybody else find it weird that Telstar and Death Star not only are phonetically similar, but look eerily so as well?

Sometimes editors at media outlets get a little panicked when there’s a big story swirling around and they haven’t done anything with it. It all started as a largely ignored paper about the number of positive and negative words people use in Facebook posts. Now it’s a major scandal. Yesterday the New York Times connected the Facebook experiment to suicides. The story was headlined, Should Facebook Manipulate Users, and it rests on the questionable assumption that such manipulation has happened

Neurosurgeons from the University Medical Centre Utrecht performed the extreme procedure to save the woman from a rare chronic bone disorder, which increased the thickness of her cranium from 1.5 centimeters to five centimeters and put her at risk of permanent brain damage. CAVEAT LECTOR: Inaccurate title, as it was basically the skull cap, not the entire skull but it's still notable.
